For those of you that still have programs that download data from Yahoo, please note the following:

1. A URL like this example: https://query1.finance.yahoo.com/v7/finance/chart/...

Still works as expected. The return data is a bit awkward to work with given the format - you don't get one row of data back for each day, but instead have to "splice together" the arrays of data returned for each field (open, high, low, close, adjusted close, etc). Note that adjusted close may be inaccurate as well - I've not checked that for a while.


2. A URL like this example: https://query1.finance.yahoo.com/v7/finance/downlo...

No longer works... You get the message about not being subscribed to premium. The free "download/... endpoint is gone.


Sadly, in our age of big data, free EOD data for run-of-the-mill stock prices seems to be getting harder to find, not easier. Moving over to the URL like #1 above is not a big effort, but of course there's also a chance that will no longer work in the future as well.

If anyone has a reliable source for free EOD data that's reasonably well-maintained, I'm all ears!
